چکیده
Abstract The increasing penetration of stochastic renewable energy has raised interest in storage to supply electricity on demand. Batteries are currently the preferred solution but concerns about their environmental impact remain. An alternative can be Compressed Air Energy Storage (CAES), which is intrinsically more flexible since, contrary batteries, capacity and power rating decoupled. In this study, we present a detailed thermodynamic model multistage quasi-isothermal CAES, optimized increase photovoltaic (PV) self-consumption micro-grid located Switzerland. A Genetic Algorithm (GA) optimization applied determine best operation schedule as well sizing parametric study performed for various ratios PV generation load. Our results show that multi-family house already invested system, adding CAES not economically viable level below 50 kW. However, could become cost-effective microgrids with large share, since cost energy-related part rather low compared power-related part, making it suitable longer-term solutions (in comparison batteries).

15 صفحه اولUsing Dynamic Thermal Rating and Energy Storage Systems Technologies Simultaneously for Optimal Integration and Utilization of Renewable Energy Sources
Nowadays, optimal integration and utilization of renewable energy sources (RES) are of the most challenging issues in power systems. The wind and solar generation units' maximum production may or may not occur at peak consumption times resulting in non-optimal utilization of these resources. As a solution to this problem, energy storage systems (ESS) are embedded in networks. However, the power...
